For uncompromising quality in precision pH measurements, the Model H-PH-1 combination electrode measures the pH potential against a reference, covering a pH range of 0 to 14. With a stem diameter of only 3mm and a length of 180mm, this pH electrode is ideal for measuring small sample volumes contained within 5mm OD, or larger, NMR tubes, as it requires only 7mm immersion depth for accurate measurements. The electrode includes a standard S7 connector. Additional quantities of electrolyte solutions are sold separately.

Please Note: pH electrodes do not come with connecting cables. These need to be ordered separately.
